SQL Min/Max Syntax

SQL’s MIN/MAX syntax is supported in beta. To enable it, first run

SET paradedb.enable_aggregate_custom_scan TO on;

With this feature enabled, the following query is equivalent to the above and is executed in the same way.

Min

SELECT MIN(rating) FROM mock_items
WHERE id @@@ pdb.all();

By default, MIN/MAX ignore null values. Use COALESCE to include them in the final sum:

SELECT MIN(COALESCE(rating, 0)) FROM mock_items
WHERE id @@@ pdb.all();
